electrak has led the power distribution market for cavity fl oor solutions since 1984 when

it launched the fi rst small power track system. With minimal parts and push-fi t assembly,

this fl exible system is easy to install and minimises disruption as offi ce layouts evolve.

deSIgn and InStaLLatIOn

The system consists of continuous lengths of track

(generally arranged in parallel format) which are fed from

the distribution board via track feed boxes and can be

installed in fl oor voids as low as 48 mm.

Track lengths fi t together using integral track connectors

for quick assembly with access to power via tap-offs from

the shuttered outlets.

■ General installation notesElectrak power track is a compact system that can be installed in floorvoids as low as 48 mm

Track feed boxes are provided with one or two 25 mm diameter holessuitable for MICC, armoured cables or single core cables in conduitTrack lengths connect together and to track feeds using the integralconnectors on each length

Track lengths should always be secured using the integral floor fixingbrackets ; three on the 3·6 m length and two on 2·4 m or 1·2 m lengthsAccess to power is provided along the track length by simply pluggingtap-off units into shuttered socket outlets. These tap-off units feed alltypes of conventional floor service outlet boxes or feed workstationsdirectly through the floor via 4 mm2 or 1·5 mm2 insulated conductorscontained in flexible metal or VO rated nylon conduit. When connectingtap-offs directly through the floor via grommet outlets to workstationscare must be taken to ensure that the tap-off length is adequate

The dual power track system has both standard and low noise / cleanearth systems incorporated. As well as dual tap-offs, both standardand low noise / clean earth tap-offs can be plugged into any socketoutlet along the track length. The dual tap-off incorporates bothstandard and low noise cables

Optimum layout flexibility is achieved by positioning track lengths amaximum of 5·2 m apart and 2·5 m from the wall, and by connectingthe 3 m tap-off units to floor outlet boxes. This means every part of thefloor area can be served. Flexible interlinks can be used to overcomeobstructions or used as corners if required

■ Special fixing bracketsWhen installing track off-floor, Electrak special fixing brackets raisetrack by 21 mm. Ensure brackets are spaced 600 mm apart andalways have support under the integral track connector and track feed.Failure to do so may undermine the integrity of the system

DZ1210 raised off-floor fixing brackets are spaced at 600 mm centresalong track. Also use bottom half of bracket under track feed andflexible interlinkDZ1230 raised off-floor fixing brackets are always used under integraltrack connectors. Track is secured to raised brackets using the track’sintegral fixing bracket

Electrak® power track systemstechnical information

■ Earth fault loop impedanceBS 7671 : 2008 IEE Wiring Regulations require accurate determinationof the total earth loop impedance, which must be sufficiently low toallow the protective device to operate within the specified time, whichfor socket outlets is 0·4 seconds. The values relevant to Electrak forcalculating the earth fault loop impedance are shown in the electricaltest data table, see opposite

■ DurabilityElectrak systems are superbly designed and extremely robust. Theycan be expected to stand up to all normal site conditions. Electrak hasbeen short circuit strength tested by ASTA

■ Installations with high protective conductor currentsAll unfused tap-offs comply with Regulation 543·7 without the need foradditional earth conductors. Regulation 543·7·1·3 (ii) states “a singlecopper protective conductor having a cross-sectional area of not lessthan 4 mm2, complying with the requirements of Regulations 543·2 and543·3, the protective conductor being enclosed to provide additionalprotection against mechanical damage, for example, within a flexibleconduit”For 543·7 installations with high protective conductor currents requiringfused tap-offs, a 543·7 compliant tap-off must be used. Normally fusedtap-offs incorporate 1·5 mm2 conductors, however in the fused 543·7tap-offs, the 1·5 mm2 earth conductor is replaced with a 4 mm2

conductor and therefore complies with Section 543·7·1·3 (ii)

■ 32 A tap-off unitThe 32 A tap-off unit comprises an unfused tap-off with either 2·8 m of16 mm / 20 mm diameter flexible metal conduit or VO rated nylonconduit both with integral 4 mm2 LSOH conductors

These units are designed to comply with regulation 434·2·1 of the IEE Wiring Regulations by virtue of the following :• maximum length of cable is 3 m• it is factory assembled and fully tested item with cable installed inhigh quality flexible conduit

Fault condition protection for the tap-off assembly and the floor boxsocket outlets is delivered by the circuit protection deviceDisconnection time for socket outlets is 0·4 seconds (Regulation411·3·2·2). The Electrak system meets this requirement

Tap-off units in excess of 3 m should only be used if they contain afuse or the power track is protected by a 32 A rated protective device
